Shirley has a point; there may be a file/folder that has had it's permissions changed so that the admin. group is barred from access.
it's kind of a moot point for an admin. as he (or she) still has the right to grant access to it.
you probably could right-click the root Demigod folder and tell it to force some nice rules on all subfiles and folders; as long as the new permissions will allow you and the program access then overwriting the existing permissions shouldn't do any harm.

I thought of all this already and tried it, i've also got no programs like antivirus that could be causing a problem like this.
I noticed after reinstalling the game it says : Vista users run the game from vista "game explorer" but I don't have this thing? could that be the problem? the game won't even run from the CD-autorun menu..
